A series of Li 2 CO 3 ‐added ( Ba 0.95 Ca 0.05 )( Ti 0.90 Sn 0.10 ) O BCTS ceramics were prepared by normal sintering at a low temperature 1300°C; Their microstructure and electrical property evaluation investigated with special emphases on the effect addition. Adding significantly improves sinterability ceramics, resulting in reduced more than 150°C. The coexistence R T phases is confirmed Raman spectrum room for all samples range from −80°C to 40°C sample 3% mol specific ratio phase...
Abstract Dielectric capacitors are strikingly attractive for use in advanced high‐power pulsed‐discharge devices electronic systems. However, their poor energy‐storage density ( U rec ) and efficiency η resulting from the large remanent polarization P r low breakdown strength (BDS), have been major challenge practical applications. Inspired by glass ceramics which core‐shell microstructure is considered an effective method to improve BDS, maintain max , reduce values, strategy of...
Abstract High mechanical quality factor ( Q m ) and low loss are crucial for the performance of piezoelectric materials in high‐power applications. Although potassium sodium niobate (KNN) based ceramics promising candidates lead‐free due to their favorable environmental benefits, they traditionally face a trade‐off between high coefficient d 33 . To address this long‐standing issue, multivalent acceptor codoping strategy is presented that innovatively induces hierarchical domain structure...
The hydrogen embrittlement property of a prototype 1700-MPa-class ultrahigh-strength steel (NIMS17) containing traps was evaluated using slow strain rate test (SSRT) after cathodic precharging, cyclic corrosion (CCT) and atmospheric exposure. content in fractured specimen measured SSRT by thermal desorption spectroscopy (TDS). relationship between fracture stress for the hydrogen-precharged specimens showed that NIMS17 higher, at given content, than conventional AISI 4135 steels with tensile...
The Li/Ta‐codoped lead‐free (Na,K)NbO 3 ceramics with Na:K ratio of 0.535:0.480 were prepared by normal sintering, whose nominal formula was noted as [(Na 0.535 K 0.480 ) 0.942 Li 0.058 ](Nb 1− x Ta )O ( =2, 4, 6, 8, 10, 12, 14, and 16 at.%). X‐ray diffraction patterns the corresponding calculation lattice parameters showed that a morphotropic phase boundary crossing orthorhombic tetragonal symmetries occurs at compositions containing 6∼8 at.% Ta. Because such transitional behavior achieved...
The corrosion behavior of AZ31 Mg alloy in the nondeaerated and deaerated dilute NaCl solutions was investigated by electrochemical measurements. cathodic reaction depends on hydrogen evolution oxygen reduction media, while that is dominanted media. In potentiostatic measurements current density reached a peak during initial immersion then showed stepwise decrease getting into passivation state homogeneous distribution Mg(OH)2 product with increasing polarization time. It revealed has better...
